To aZlNwho-m 'it may concern:

B e it known that I, WILLIAM W. NUGENT,

a citizen of the United States, residing at.

-ties or to remove foreign matter from liquids, and as such it has for its primary A object to. provide a convenient, simple and inexpenslve device which is eiective and efficient in operation.

Another object is to provide filtering elements which are rotatable, interchangeable and removable.

The invention. consists in the construction, combination and arrangement generally described in the specication and more particularly pointed out in the claims.

In the accompanying drawings, F1gure 1 is a sectional elevation of an embodiment of `my invention. Fig. 2 is a plan view of the filtering devices. Fig. 3 is a plan View of the storage chamber and the cocks connected thereto.4 Fig. 4 is a detail view of the engaginglips of the lter holder members. Fig. 5 shows a modification of Fig. 1.

Referring naw more particularly to the` drawings the receptacle 5 is preferably mounted uponpthe storage chamber or section 6 and is provided with a sliding door 7 which communicateswith the interior of the receptacle. A- tray' 8 is provided which is adapted to be inserted in the receptacle 5 at its upper end, the upper edge of the tray 8 engaging the upper edge of the receptacle 5. In the bottom of this tray 8, an axle bolt 9 isv secured vand the bottom of the tray is suitably 'strengthened by the braces 10.` These braces 10 extend upwardly providing a passageway for. liquid in the interstices between the braces and being adapted by ltheir Aupward projection to provide a support for a second tray 11, 'which does not extend above the edge 'of the iirst tray 8. In thebottom of tray 11 is an opening about which yan inverted cone 11 of reticulated material is placed. A lid 12 extends over the edges of the trays and of the receptacle.5 providing a cover therefor.

A collar. 13 is rotatable about the axle bolt 9 and is provided with a plurality of openings '14 in which a project-ing lug 15 of a filtering device 16 is adapted to be inserted. These filtering devices are formed with a supporting frame preferably of a funnel-,shape formation arrangedin a series of converging steps through which are concentric apertures 17. In the outer surface of these frames are grooves 18, and a plurality of reticulated sacks or receivers 19 are adapted to be arranged one within the other and to be secured in the said grooves by means of rings 20. These receivers19 are preferably of a successive ineness of mesh `and are arranged so that the one ofl finest mesh is outside. It will be noticed that the receivers are arranged so that the one of smallest diameter is within the others and is preferably'arranged so that its upper edge is lower than that of each succeeding receiver.

In the tray 8, directly above and in line .with lthe filtering devices as they yare arranged about the axle bolt 9, are stop cocks 21, and by reference to Fig. 2 it will be seen that they are arranged in accordanc'evwith the arrangement of the saidfiltering devices, one of the stop cocks being omitted in the present exemplication for the purpose of facilitating the removal of any one of the filtering devices for the purposes of adjust ment or cleaning. Since these filtering devices are all alike, it is evident that they are interchangeable and may be readily' removed from the receptacle when the sliding door 7 is opened without interfering or disturbing the flow of oil to the other filtering ,devices 4 M Adjacent the bottom of the receptacle 5 is a heating coil 22 with outside connections 23, the purpose and object of the same being to heat the Huid in its filtered condition thereby facilitating its passage into the lower chamber by rendering it more viscous. In the bottom 24 of the receptacle is an opening 25 which .is provided lwith a reticu\ lated partition 26 opening into a funnel shaped receiver 27 in the receiving chamber 6. This funnel 27 communicates with the downwardly extending pipe 28 which has an opening near the bottom of 'the .Saldi chamber but does not extend entirely to the floor thereof. In the storage Chamber 6 into ywhich the pipe 28 extends 1s .a sectional partition 29 embracing in the present embodiment substantially one quarter of the chamber. This partition extends upwardl and the fluidI which comes down throng the pipe 28 fills the sectional portion of the chamber and flows over the partition 29 into the larger compartment. In this storage sectionof the filter the water gage cock 30 and the water sealing outlet device 34 are connected with the sectional portion, and

the oil gage cock 3l, the oil faucet 32 andl the outlet plug 33 are connected with the larger compartment. also shown in Fig. 3.

Thus it is seen that a liquid to be ltered is poured in the upper tray 11 and passes downward throughs the c'one of reticulated material and the opening in the bottom of the first tray to the tray 8 to remove any foreign matters from the liquid.- From the tray 8 the liquid is directed downwardly through the cocksv 2l into the`filtering devices, and from the latter through the opening into the storage chamber below.

The holders 16 are preferably composed of a series of members with engaging lips 36 (see Figs. 1 and 4). Each member supports one of the reticulated receivers 19 and is removable from within the next larger receiver without disturbing it or any of the other receivers and without interfering with the filtering action. The function of the apertures 17 and the utility of the funnel Shape is clearly evident: for if the innermost receiver into which the fluid is directed, becomes clogged or does not dispose of the iuid rapidly enough, the fluid overflows into the next receiver through the apertures 17, the upper edge of the next receiver being higher than that of the lled receiver.

When the fluid to be filtered is a mixture of oil and water, the bottom or storage section is adapted to separate the water from the oil in a well known manrgr, the various cocks, gages, and faucets bein arranged and provided to facilitate the withdrawal of oil and water from their respective chambers.

A'modification of Fig. 1 is shown by Fig. 5 in which one of -the upper trays is eliminated, andthe structure of the axle bolt is changed. In this exempliication the edge of the tray 36Lengagesthe edge of the receptacle 5, the tray supporting the axle bolt 37 This bolt 37 is preferably attached adjacent the center of the tray-and is formed with a hollowed out portion 38 vwhich opens into the tray and over whichl opening the filter cone 11 of reticulated 55 material is placed. .Opening out-from the h llowed out portion 38 are a number of -passageways 39 into which the pipes 40 are fitted, At the end of each pipe 40 there is' placed a stop-cock 21 which 1s adapted to control the flow of Huid to the filtering members below, as previously set forth. In

Athis modification it is necessary to provide the bolt 37 i .with a nut and threaded portion at its lower end, and the collar 141s preferablyprovided ,with slots in whicha pin A drip apron 35 Iis' 42 positioned in a holethrough the bolt is adapted to engage `when the collar is seated at the end of the bolt 37. The object of this arrangement is toretain the filtering receptacles in position below the` stop cocks 21. The collar 14 and the holders 16 are freely movable and the collar may be rotated with respect to the bolt 37 by lifting it up free of the pin 42.

Although I have indicated that four liltering receivers are employed, it is contemplated that any number may beused, and that various other changes may be made without departing from the spirit and scope of the invention.
